Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult

RubyMine

  • No permanently free tier for commercial use; requires an ongoing subscription
  • More resource-intensive than lightweight editors such as Sublime Text
  • Focused primarily on Ruby, so polyglot teams may prefer IntelliJ IDEA Ultimate with plugins instead
  • Startup time can be slower than simpler text editors on older hardware
